This paper presents the results of the first round of benchmarking measurements of material samples relevant to 5G/mmWave technologies. The benchmarking initiative has been set up by an international and intersectoral consortium of 25 partners who will perform round-robin testing of representative low Dk / Df materials with the use of a range of microwave and millimetre-wave techniques. In the first round, three GHz resonator techniques (SCR, SPDR, FPOR) have been applied to COP and Teflon samples at three laboratories. The results show a remarkable agreement both between the techniques and between the laboratories. Measurement repeatability is also evaluated, according to the industrial practice. The reported data provide a ‘place holder’ until SRMs are defined by standards organisations, for which this work provides background.
